Thanks for the infomation. Since both getServletNames() and getServlet()
functions are deprecated, what function call should I use to replace
them? Or maybe use an entire different approach to have communications
between servlets?

That's because getServlet() and getServletNames() were not just deprecated,
but disabled in the JSDK 2.1 spec. All JSDK 2.1 compliant servlet engines
are required to return an empty Enumeration for getServletNames(), and null
for getServlet().
